DETAILED DESCRIPTION

Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and systems for multi-modal transmission of packetized data in a voice activated data packet based computer network environment. The various concepts introduced above and discussed in greater detail below may be implemented in any of numerous ways.

Systems and methods of the present disclosure relate generally to a data processing system that identifies an optimal transmission modality for data packet (or other protocol based) transmission in a voice activated computer network environment. The data processing system can improve the efficiency and effectiveness of data packet transmission over one or more computer networks by, for example, selecting a transmission modality from a plurality of options for data packet routing through a computer network of content items to one or more client computing device, or to different interfaces (e.g., different apps or programs) of a single client computing device. Data packets or other protocol based signals corresponding to the selected operations can be routed through a computer network between multiple computing devices. For example the data processing system can route a content item to a different interface than an interface from which a request was received. The different interface can be on the same client computing device or a different client computing device from which a request was received. The data processing system can select at least one candidate interface from a plurality of candidate interfaces for content item transmission to a client computing device. The candidate interfaces can be determined based on technical or computing parameters such as processor capability or utilization rate, memory capability or availability, battery status, available power, network bandwidth utilization, interface parameters or other resource utilization values. By selecting an interface to receive and provide the content item for rendering from the client computing device based on candidate interfaces or utilization rates associated with the candidate interfaces, the data processing system can reduce network bandwidth usage, latency, or processing utilization or power consumption of the client computing device that renders the content item. This saves processing power and other computing resources such as memory, reduces electrical power consumption by the data processing system and the reduced data transmissions via the computer network reduces bandwidth requirements and usage of the data processing system.

The systems and methods described herein can include a data processing system that receives an input audio query, which can also be referred to as an input audio signal. From the input audio query the data processing system can identify a request and a trigger keyword corresponding to the request. Based on the trigger keyword or the request, the data processing system can generate a first action data structure. For example, the first action data structure can include an organic response to the input audio query received from a client computing device, and the data processing system can provide the first action data structure to the same client computing device for rendering as audio output via the same interface from which the request was received.

The data processing system can also select at least one content item based on the trigger keyword or the request. The data processing system can identify or determine a plurality of candidate interfaces for rendering of the content item(s). The interfaces can include one or more hardware or software interfaces, such as display screens, audio interfaces, speakers, applications or programs available on the client computing device that originated the input audio query, or on different client computing devices. The interfaces can include java script slots for online documents for the insertion of content items, as well as push notification interfaces. The data processing system can determine utilization values for the different candidate interfaces. The utilization values can indicate power, processing, memory, bandwidth, or interface parameter capabilities, for example. Based on the utilization values for the candidate interfaces the data processing system can select a candidate interface as a selected interface for presentation or rendering of the content item. For example, the data processing system can convert or provide the content item for delivery in a modality compatible with the selected interface. The selected interface can be an interface of the same client computing device that originated the input audio signal or a different client computing device. By routing data packets via a computing network based on utilization values associated with a candidate interface, the data processing system selects a destination for the content item in a manner that can use the least amount of processing power, memory, or bandwidth from available options, or that can conserve power of one or more client computing devices.

The data processing system can provide the content item or the first action data structure by packet or other protocol based data message transmission via a computer network to a client computing device. The output signal can cause an audio driver component of the client computing device to generate an acoustic wave, e.g., an audio output, which can be output from the client computing device. The audio (or other) output can correspond to the first action data structure or to the content item. For example the first action data structure can be routed as audio output, and the content item can be routed as a text based message. By routing the first action data structure and the content item to different interfaces, the data processing system can conserve resources utilized by each interface, relative to providing both the first action data structure and the content item to the same interface. This results in fewer data processing operations, less memory usage, or less network bandwidth utilization by the selected interfaces (or their corresponding devices) than would be the case without separation and independent routing of the first action data structure and the content item.

The data processing system can identify one or more devices within range of a computing device that detects an input audio signal via a microphone. The data processing system can poll the one or more identified devices within range to identify one or more candidate interfaces. The data processing system can determine a resource utilization value for each of the one or more candidate interfaces in order to select an interface via which to transmit a notification or content item. For example, the data processing system can determine to transmit a content item or a notification. The data processing system can determine to transmit the content item or the notification responsive to voice input received by a computing device. Prior to transmission of the content item or the notification, the data processing system can identify one more computing devices within range of the computing device. The data processing system can poll the plurality of computing devices to identify candidate interfaces for the content item. The data processing system can determine, for example, that a first candidate interface of a first computing device has a high resource utilization value (e.g., the first candidate interface can be an audio interface and the data processing system can determine that the first computing device is playing music). The data processing system can determine that a second candidate interface has a low resource utilization value (e.g., the second candidate interface can include a visual display that is not currently in use). The data processing system can further determine that the content item can be presented in either audio format or a visual format. The data processing system can then select the second candidate interface, convert or select the content item in the visual format, and transmit the candidate content item for presentation via the second candidate interface.

FIG. 1 depicts an example system 100 to for multi-modal transmission of packetized data in a voice activated data packet (or other protocol) based computer network environment. The system 100 can include at least one data processing system 105. The data processing system 105 can include at least one server having at least one processor. For example, the data processing system 105 can include a plurality of servers located in at least one data center or server farm. The data processing system 105 can determine, from an audio input signal a request and a trigger keyword associated with the request. Based on the request and trigger keyword the data processing system 105 can determine or select at least one action data structure, and can select at least one content item (and initiate other actions as described herein). The data processing system 105 can identify candidate interfaces for rendering of the action data structures or the content items, and can provide the action data structures or the content items for rendering by one or more candidate interfaces on one or more client computing devices based on resource utilization values for or of the candidate interfaces, for example as part of a voice activated communication or planning system. The action data structures (or the content items) can include one or more audio files that when rendered provide an audio output or acoustic wave. The action data structures or the content items can include other content (e.g., text, video, or image content) in addition to audio content.

The data processing system 105 can include multiple, logically-grouped servers and facilitate distributed computing techniques. The logical group of servers may be referred to as a data center, server farm or a machine farm. The servers can be geographically dispersed. A data center or machine farm may be administered as a single entity, or the machine farm can include a plurality of machine farms. The servers within each machine farm can be heterogeneous—one or more of the servers or machines can operate according to one or more type of operating system platform. The data processing system 105 can include servers in a data center that are stored in one or more high-density rack systems, along with associated storage systems, located for example in an enterprise data center. The data processing system 105 with consolidated servers in this way can improve system manageability, data security, the physical security of the system, and system performance by locating servers and high performance storage systems on localized high performance networks. Centralization of all or some of the data processing system 105 components, including servers and storage systems, and coupling them with advanced system management tools allows more efficient use of server resources, which saves power and processing requirements and reduces bandwidth usage.

The network 165 can include computer networks such as the internet, local, wide, metro or other area networks, intranets, satellite networks, other computer networks such as voice or data mobile phone communication networks, and combinations thereof.

The network 165 can include or constitute a display network, e.g., a subset of information resources available on the internet that are associated with a content placement or search engine results system, or that are eligible to include third party content items as part of a content item placement campaign. The network 165 can be used by the data processing system 105 to access information resources such as web pages, web sites, domain names, or uniform resource locators that can be presented, output, rendered, or displayed by the client computing device 150. For example, via the network 165 a user of the client computing device 150 can access information or data provided by the data processing system 105, the content provider computing device 155 or the service provider computing device 160.

The network 165 can include, for example a point-to-point network, a broadcast network, a wide area network, a local area network, a telecommunications network, a data communication network, a computer network, an ATM (Asynchronous Transfer Mode) network, a SONET (Synchronous Optical Network) network, a SDH (Synchronous Digital Hierarchy) network, a wireless network or a wireline network, and combinations thereof. The network 165 can include a wireless link, such as an infrared channel or satellite band. The topology of the network 165 may include a bus, star, or ring network topology. The network 165 can include mobile telephone networks using any protocol or protocols used to communicate among mobile devices, including advanced mobile phone protocol (“AMPS”), time division multiple access (“TDMA”), code-division multiple access (“CDMA”), global system for mobile communication (“GSM”), general packet radio services (“GPRS”) or universal mobile telecommunications system (“UMTS”). Different types of data may be transmitted via different protocols, or the same types of data may be transmitted via different protocols.

The client computing device 150, the content provider computing device 155, and the service provider computing device 160 can each include at least one logic device such as a computing device having a processor to communicate with each other or with the data processing system 105 via the network 165. The client computing device 150, the content provider computing device 155, and the service provider computing device 160 can each include at least one server, processor or memory, or a plurality of computation resources or servers located in at least one data center. The client computing device 150, the content provider computing device 155, and the service provider computing device 160 can each include at least one computing device such as a desktop computer, laptop, tablet, personal digital assistant, smartphone, portable computer, server, thin client computer, virtual server, or other computing device.

The client computing device 150 can include at least one sensor 151, at least one transducer 152, at least one audio driver 153, and at least one speaker 154. The sensor 151 can include a microphone or audio input sensor. The transducer 152 can convert the audio input into an electronic signal, or vice-versa. The audio driver 153 can include a script or program executed by one or more processors of the client computing device 150 to control the sensor 151, the transducer 152 or the audio driver 153, among other components of the client computing device 150 to process audio input or provide audio output. The speaker 154 can transmit the audio output signal.

The client computing device 150 can be associated with an end user that enters voice queries as audio input into the client computing device 150 (via the sensor 151) and receives audio output in the form of a computer generated voice that can be provided from the data processing system 105 (or the content provider computing device 155 or the service provider computing device 160) to the client computing device 150, output from the speaker 154. The audio output can correspond to an action data structure received from the direct action API 135, or a content item selected by the content selector component 125. The computer generated voice can include recordings from a real person or computer generated language.

The content provider computing device 155 (or the data processing system 105 or service provider computing device 160) can provide audio based content items or action data structures for display by the client computing device 150 as an audio output. The action data structure or content item can include an organic response or offer for a good or service, such as a voice based message that states: “Today it will be sunny and 80 degrees at the beach” as an organic response to a voice-input query of “Is today a beach day?”. The data processing system 105 (or other system 100 component such as the content provider computing device 155 can also provide a content item as a response, such as a voice or text message based content item offering sunscreen.

The content provider computing device 155 or the data repository 145 can include memory to store a series of audio action data structures or content items that can be provided in response to a voice based query. The action data structures and content items can include packet based data structures for transmission via the network 165. The content provider computing device 155 can also provide audio or text based content items (or other content items) to the data processing system 105 where they can be stored in the data repository 145. The data processing system 105 can select the audio action data structures or text based content items and provide (or instruct the content provider computing device 155 to provide) them to the same or different client computing devices 150 responsive to a query received from one of those client computing device 150. The audio based action data structures can be exclusively audio or can be combined with text, image, or video data. The content items can be exclusively text or can be combined with audio, image or video data.

The service provider computing device 160 can include at least one service provider natural language processor (NLP) component 161 and at least one service provider interface 162. The service provider NLP component 161 (or other components such as a direct action API of the service provider computing device 160) can engage with the client computing device 150 (via the data processing system 105 or bypassing the data processing system 105) to create a back-and-forth real-time voice or audio based conversation (e.g., a session) between the client computing device 150 and the service provider computing device 160. For example, the service provider interface 162 can receive or provide data messages (e.g., action data structures or content items) to the direct action API 135 of the data processing system 105. The direct action API 135 can also generate the action data structures independent from or without input from the service provider computing device 160. The service provider computing device 160 and the content provider computing device 155 can be associated with the same entity. For example, the content provider computing device 155 can create, store, or make available content items for beach relates services, such as sunscreen, beach towels or bathing suits, and the service provider computing device 160 can establish a session with the client computing device 150 to respond to a voice input query about the weather at the beach, directions for a beach, or a recommendation for an area beach, and can provide these content items to the end user of the client computing device 150 via an interface of the same client computing device 150 from which the query was received, a different interface of the same client computing device 150, or an interface of a different client computing device. The data processing system 105, via the direct action API 135, the NLP component 110 or other components can also establish the session with the client computing device, including or bypassing the service provider computing device 160, to for example to provide an organic response to a query related to the beach.

The data repository 145 can include one or more local or distributed databases, and can include a database management system. The data repository 145 can include computer data storage or memory and can store one or more parameters 146, one or more policies 147, content data 148, or templates 149 among other data. The parameters 146, policies 147, and templates 149 can include information such as rules about a voice based session between the client computing device 150 and the data processing system 105 (or the service provider computing device 160). The content data 148 can include content items for audio output or associated metadata, as well as input audio messages that can be part of one or more communication sessions with the client computing device 150.

The system 100 can optimize processing of action data structures and content items in a voice activated data packet (or other protocol) environment. For example, the data processing system 105 can include or be part of a voice activated assistant service, voice command device, intelligent personal assistant, knowledge navigator, event planning, or other assistant program. The data processing system 105 can provide one or more instances of action data structures as audio output for display from the client computing device 150 to accomplish tasks related to an input audio signal. For example, the data processing system can communicate with the service provider computing device 160 or other third party computing devices to generate action data structures with information about a beach, among other things. For example, an end user can enter an input audio signal into the client computing device 150 of: “OK, I would like to go to the beach this weekend” and an action data structure can indicate the weekend weather forecast for area beaches, such as “it will be sunny and 80 degrees at the beach on Saturday, with high tide at 3 pm.”

The action data structures can include a number of organic or non-sponsored responses to the input audio signal. For example, the action data structures can include a beach weather forecast or directions to a beach. The action data structures in this example include organic, or non-sponsored content that is directly responsive to the input audio signal. The content items responsive to the input audio signal can include sponsored or non-organic content, such as an offer to buy sunscreen from a convenience store located near the beach. In this example, the organic action data structure (beach forecast) is responsive to the input audio signal (a query related to the beach), and the content item (a reminder or offer for sunscreen) is also responsive to the same input audio signal. The data processing system 105 can evaluate system 100 parameters (e.g., power usage, available displays, formats of displays, memory requirements, bandwidth usage, power capacity or time of input power (e.g., internal battery or external power source such as a power source from a wall output) to provide the action data structure and the content item to different candidate interfaces on the same client computing device 150, or to different candidate interfaces on different client computing devices 150.

The data processing system 105 can include an application, script or program installed at the client computing device 150, such as an app to communicate input audio signals (e.g., as data packets via a packetized or other protocol based transmission) to at least one interface 115 of the data processing system 105 and to drive components of the client computing device 150 to render output audio signals (e.g., for action data structures) or other output signals (e.g., content items). The data processing system 105 can receive data packets or other signal that includes or identifies an audio input signal. For example, the data processing system 105 can execute or run the NLP component 110 to receive the audio input signal.

The NLP component 110 can convert the audio input signal into recognized text by comparing the input signal against a stored, representative set of audio waveforms (e.g., in the data repository 145) and choosing the closest matches. The representative waveforms are generated across a large set of users, and can be augmented with speech samples. After the audio signal is converted into recognized text, the NLP component 110 can match the text to words that are associated, for example via training across users or through manual specification, with actions that the data processing system 105 can serve.

The audio input signal can be detected by the sensor 151 (e.g., a microphone) of the client computing device. Via the transducer 152, the audio driver 153, or other components the client computing device 150 can provide the audio input signal to the data processing system 105 (e.g., via the network 165) where it can be received (e.g., by the interface 115) and provided to the NLP component 110 or stored in the data repository 145 as content data 148.

The NLP component 110 can receive or otherwise obtain the input audio signal. From the input audio signal, the NLP component 110 can identify at least one request or at least one trigger keyword corresponding to the request. The request can indicate intent or subject matter of the input audio signal. The trigger keyword can indicate a type of action likely to be taken. For example, the NLP component 110 can parse the input audio signal to identify at least one request to go to the beach for the weekend. The trigger keyword can include at least one word, phrase, root or partial word, or derivative indicating an action to be taken. For example, the trigger keyword “go” or “to go to” from the input audio signal can indicate a need for transport or a trip away from home. In this example, the input audio signal (or the identified request) does not directly express an intent for transport, however the trigger keyword indicates that transport is an ancillary action to at least one other action that is indicated by the request.

The prediction component 120 (or other mechanism of the data processing system 105) can generate, based on the request or the trigger keyword, at least one action data structure associated with the input audio signal. The action data structure can indicate information related to subject matter of the input audio signal. The action data structure can include one or more than one action, such as organic responses to the input audio signal. For example, the input audio signal “OK, I would like to go to the beach this weekend” can include at least one request indicating an interest for a beach weather forecast, surf report, or water temperature information, and at least one trigger keyword, e.g., “go” indicating travel to the beach, such as a need for items one may want to bring to the beach, or a need for transportation to the beach. The prediction component 120 can generate or identify subject matter for at least one action data structure, an indication of a request for a beach weather forecast, as well as subject matter for a content item, such as an indication of a query for sponsored content related to spending a day at a beach. From the request or the trigger keyword the prediction component 120 (or other system 100 component such as the NLP component 110 or the direct action API 135) predicts, estimates, or otherwise determines subject matter for action data structures or for content items. From this subject matter, the direct action API 135 can generate at least one action data structure and can communicate with at least one content provider computing device 155 to obtain at least one content item 155. The prediction component 120 can access the parameters 146 or policies 147 in the data repository 145 to determine or otherwise estimate requests for action data structures or content items. For example, the parameters 146 or policies 147 could indicate requests for a beach weekend weather forecast action or for content items related to beach visits, such as a content item for sunscreen.

The content selector component 125 can obtain indications of any of the interest in or request for the action data structure or for the content item. For example, the prediction component 120 can directly or indirectly (e.g., via the data repository 145) provide an indication of the action data structure or content item to the content selector component 125. The content selector component 125 can obtain this information from the data repository 145, where it can be stored as part of the content data 148. The indication of the action data structure can inform the content selector component 125 of a need for area beach information, such as a weather forecast or products or services the end user may need for a trip to the beach.

From the information received by the content selector component 125, e.g., an indication of a forthcoming trip to the beach, the content selector component 125 can identify at least one content item. The content item can be responsive or related to the subject matter of the input audio query. For example, the content item can include data message identifying as tore near the beach that has sunscreen, or offering a taxi ride to the beach. The content selector component 125 can query the data repository 145 to select or otherwise identify the content item, e.g., from the content data 148. The content selector component 125 can also select the content item from the content provider computing device 155. For example responsive to a query received from the data processing system 105, the content provider computing device 155 can provide a content item to the data processing system 105 (or component thereof) for eventual output by the client computing device 150 that originated the input audio signal, or for output to the same end user by a different client computing device 150.

The audio signal generator component 130 can generate or otherwise obtain an output signal that includes the content item (as well as the action data structure) responsive to the input audio signal. For example, the data processing system 105 can execute the audio signal generator component 130 to generate or create an output signal corresponding to the action data structure or to the content item. The interface component 115 of the data processing system 105 can provide or transmit one or more data packets that include the output signal via the computer network 165 to any client computing device 150. The interface 115 can be designed, configured, constructed, or operational to receive and transmit information using, for example, data packets. The interface 115 can receive and transmit information using one or more protocols, such as a network protocol. The interface 115 can include a hardware interface, software interface, wired interface, or wireless interface. The interface 115 can facilitate translating or formatting data from one format to another format. For example, the interface 115 can include an application programming interface that includes definitions for communicating between various components, such as software components of the system 100.

The data processing system 105 can provide the output signal including the action data structure from the data repository 145 or from the audio signal generator component 130 to the client computing device 150. The data processing system 105 can provide the output signal including the content item from the data repository 145 or from the audio signal generator component 130 to the same or to a different client computing device 150.

The data processing system 105 can also instruct, via data packet transmissions, the content provider computing device 155 or the service provider computing device 160 to provide the output signal (e.g., corresponding to the action data structure or to the content item) to the client computing device 150. The output signal can be obtained, generated, transformed to or transmitted as one or more data packets (or other communications protocol) from the data processing system 105 (or other computing device) to the client computing device 150.

The content selector component 125 can select the content item or the action data structure for the as part of a real-time content selection process. For example, the action data structure can be provided to the client computing device 150 for transmission as audio output by an interface of the client computing device 150 in a conversational manner in direct response to the input audio signal. The real-time content selection process to identify the action data structure and provide the content item to the client computing device 150 can occur within one minute or less from the time of the input audio signal and be considered real-time. The data processing system 105 can also identify and provide the content item to at least one interface of the client computing device 150 that originated the input audio signal, or to a different client computing device 150.

The action data structure (or the content item), for example obtained or generated by the audio signal generator component 130 transmitted via the interface 115 and the computer network 165 to the client computing device 150, can cause the client computing device 150 to execute the audio driver 153 to drive the speaker 154 to generate an acoustic wave corresponding to the action data structure or to the content item. The acoustic wave can include words of or corresponding to the action data structure or content item.

The acoustic wave representing the action data structure can be output from the client computing device 150 separately from the content item. For example, the acoustic wave can include the audio output of “Today it will be sunny and 80 degrees at the beach.” In this example, the data processing system 105 obtains the input audio signal of, for example, “OK, I would like to go to the beach this weekend.” From this information the NLP component 110 identifies at least one request or at least one trigger keyword, and the prediction component 120 uses the request(s) or trigger keyword(s) to identify a request for an action data structure or for a content item. The content selector component 125 (or other component) can identify, select, or generate a content item for, e.g., sunscreen available near the beach. The direct action API 135 (or other component) can identify, select, or generate an action data structure for, e.g., the weekend beach forecast. The data processing system 105 or component thereof such as the audio signal generator component 130 can provide the action data structure for output by an interface of the client computing device 150. For example, the acoustic wave corresponding to the action data structure can be output from the client computing device 150. The data processing system 105 can provide the content item for output by a different interface of the same client computing device 150 or by an interface of a different client computing device 150.

The packet based data transmission of the action data structure by data processing system 105 to the client computing device 150 can include a direct or real-time response to the input audio signal of “OK, I would like to go to the beach this weekend” so that the packet based data transmissions via the computer network 165 that are part of a communication session between the data processing system 105 and the client computing device 150 with the flow and feel of a real-time person to person conversation. This packet based data transmission communication session can also include the content provider computing device 155 or the service provider computing device 160.

The content selector component 125 can select the content item or action data structure based on at least one request or at least one trigger keyword of the input audio signal. For example, the requests of the input audio signal “OK, I would like to go to the beach this weekend” can indicate subject matter of the beach, travel to the beach, or items to facilitate a trip to the beach. The NLP component 110 or the prediction component 120 (or other data processing system 105 components executing as part of the direct action API 135) can identify the trigger keyword “go” “go to” or “to go to” and can determine a transportation request to the beach based at least in part on the trigger keyword. The NLP component 110 (or other system 100 component) can also determine a solicitation for content items related to beach activity, such as for sunscreen or beach umbrellas. Thus, the data processing system 105 can infer actions from the input audio signal that are secondary requests (e.g., a request for sunscreen) that are not the primary request or subject of the input audio signal (information about the beach this weekend).

The action data structures and content items can correspond to subject matter of the input audio signal. The direct action API 135 can execute programs or scripts, for example from the NLP component 110, the prediction component 120, or the content selector component 125 to identify action data structures or content items for one or more of these actions. The direct action API 135 can execute a specified action to satisfy the end user's intention, as determined by the data processing system 105. Depending on the action specified in its inputs, the direct action API 135 can execute code or a dialog script that identifies the parameters required to fulfill a user request. Such code can lookup additional information, e.g., in the data repository 145, such as the name of a home automation service, or it can provide audio output for rendering at the client computing device 150 to ask the end user questions such as the intended destination of a requested taxi. The direct action API 135 can determine necessary parameters and can package the information into an action data structure, which can then be sent to another component such as the content selector component 125 or to the service provider computing device 160 to be fulfilled.

The direct action API 135 of the data processing system 105 can generate, based on the request or the trigger keyword, the action data structures. The action data structures can be generated responsive to the subject matter of the input audio signal. The action data structures can be included in the messages that are transmitted to or received by the service provider computing device 160. Based on the audio input signal parsed by the NLP component 110, the direct action API 135 can determine to which, if any, of a plurality of service provider computing devices 160 the message should be sent. For example, if an input audio signal includes “OK, I would like to go to the beach this weekend,” the NLP component 110 can parse the input audio signal to identify requests or trigger keywords such as the trigger keyword word “to go to” as an indication of a need for a taxi. The direct action API 135 can package the request into an action data structure for transmission as a message to a service provider computing device 160 of a taxi service. The message can also be passed to the content selector component 125. The action data structure can include information for completing the request. In this example, the information can include a pick up location (e.g., home) and a destination location (e.g., a beach). The direct action API 135 can retrieve a template 149 from the data repository 145 to determine which fields to include in the action data structure. The direct action API 135 can retrieve content from the data repository 145 to obtain information for the fields of the data structure. The direct action API 135 can populate the fields from the template with that information to generate the data structure. The direct action API 135 can also populate the fields with data from the input audio signal. The templates 149 can be standardized for categories of service providers or can be standardized for specific service providers. For example, ride sharing service providers can use the following standardized template 149 to create the data structure: {client_device_identifier; authentication_credentials; pick_up_location; destination_location; no_passengers; service_level}.

The content selector component 125 can identify, select, or obtain multiple content items resulting from a multiple content selection processes. The content selection processes can be real-time, e.g., part of the same conversation, communication session, or series of communications sessions between the data processing system 105 and the client computing device 150 that involve common subject matter. The conversation can include asynchronous communications separated from one another by a period of hours or days, for example. The conversation or communication session can last for a time period from receipt of the first input audio signal until an estimated or known conclusion of a final action related to the first input audio signal, or receipt by the data processing system 105 of an indication of a termination or expiration of the conversation. For example, the data processing system 105 can determine that a conversation related to a weekend beach trip begins at the time or receipt of the input audio signal and expires or terminates at the end of the weekend, e.g., Sunday night or Monday morning. The data processing system 105 that provides action data structures or content items for rendering by one or more interfaces of the client computing device 150 or of another client computing device 150 during the active time period of the conversation (e.g., from receipt of the input audio signal until a determined expiration time) can be considered to be operating in real-time. In this example the content selection processes and rendering of the content items and action data structures occurs in real time.

The interface management component 140 can poll, determine, identify, or select interfaces for rendering of the action data structures and of the content items related to the input audio signal. For example, the interface management component 140 can identify one or more candidate interfaces of client computing devices 150 associated with an end user that entered the input audio signal (e.g., “What is the weather at the beach today?”) into one of the client computing devices 150 via an audio interface. The interfaces can include hardware such as sensor 151 (e.g., a microphone), speaker 154, or a screen size of a computing device, alone or combined with scripts or programs (e.g., the audio driver 153) as well as apps, computer programs, online documents (e.g., webpage) interfaces and combinations thereof.

The interfaces can include social media accounts, text message applications, or email accounts associated with an end user of the client computing device 150 that originated the input audio signal. Interfaces can include the audio output of a smartphone, or an app based messaging device installed on the smartphone, or on a wearable computing device, among other client computing devices 150. The interfaces can also include display screen parameters (e.g., size, resolution), audio parameters, mobile device parameters, (e.g., processing power, battery life, existence of installed apps or programs, or sensor 151 or speaker 154 capabilities), content slots on online documents for text, image, or video renderings of content items, chat applications, laptops parameters, smartwatch or other wearable device parameters (e.g., indications of their display or processing capabilities), or virtual reality headset parameters.

The interface management component 140 can poll a plurality of interfaces to identify candidate interfaces. Candidate interfaces include interfaces having the capability to render a response to the input audio signal, (e.g., the action data structure as an audio output, or the content item that can be output in various formats including non-audio formats). The interface management component 140 can determine parameters or other capabilities of interfaces to determine that they are (or are not) candidate interfaces. For example, the interface management component 140 can determine, based on parameters 146 of the content item or of a first client computing device 150 (e.g., a smartwatch wearable device), that the smartwatch includes an available visual interface of sufficient size or resolution to render the content item. The interface management component 140 can also determine that the client computing device 150 that originated the input audio signal has a speaker 154 hardware and installed program e.g., an audio driver or other script to render the action data structure.

The interface management component 140 can determine utilization values for candidate interfaces. The utilization values can indicate that a candidate interface can (or cannot) render the action data structures or the content items provided in response to input audio signals. The utilization values can include parameters 146 obtained from the data repository 145 or other parameters obtained from the client computing device 150, such as bandwidth or processing utilizations or requirements, processing power, power requirements, battery status, memory utilization or capabilities, or other interface parameters that indicate the available of an interface to render action data structures or content items. The battery status can indicate a type of power source (e.g., internal battery or external power source such as via an output), a charging status (e.g., currently charging or not), or an amount of remaining battery power. The interface management component 140 can select interfaces based on the battery status or charging status.

The interface management component 140 can order the candidate interfaces in a hierarchy or ranking based on the utilization values. For example different utilization values (e.g., processing requirements, display screen size, accessibility to the end user) can be given different weights. The interface management component 140 can rank one or more of the utilization values of the candidate interfaces based on their weights to determine an optimal corresponding candidate interface for rendering of the content item (or action data structure). Based on this hierarchy, the interface management component 140 can select the highest ranked interface for rendering of the content item.

Based on utilization values for candidate interfaces, the interface management component 140 can select at least one candidate interface as a selected interface for the content item. The selected interface for the content item can be the same interface from which the input audio signal was received (e.g., an audio interface of the client computing device 150) or a different interface (e.g., a text message based app of the same client computing device 150, or an email account accessible from the same client computing device 150.

The interface management component 140 can select an interface for the content item that is an interface of a different client computing device 150 than the device that originated the input audio signal. For example, the data processing system 105 can receive the input audio signal from a first client computing device 150 (e.g., a smartphone), and can select an interface such as a display of a smartwatch (or any other client computing device for rendering of the content item. The multiple client computing devices 150 can all be associated with the same end user. The data processing system 105 can determine that multiple client computing devices 150 are associated with the same end user based on information received with consent from the end user such as user access to a common social media or email account across multiple client computing devices 150.

The interface management component 140 can also determine that an interface is unavailable. For example the interface management component 140 can poll interfaces and determine that a battery status of a client computing device 150 associated with the interface is low, or below a threshold level such as 10%. Or the interface management component 140 can determine that the client computing device 150 associated with the interface lacks sufficient display screen size or processing power to render the content item, or that the processor utilization rate is too high, as the client computing device is currently executing another application, for example to stream content via the network 165. In these and other examples the interface management component 140 can determine that the interface is unavailable and can eliminate the interface as a candidate for rendering the content item or the action data structure.

Thus, the interface management component 140 can determine that a candidate interface accessible by the first client computing device 150 is linked to an account of an end user, and that a second candidate interface accessible by a second client computing device 150 is also linked to the same account. For example, both client computing devices 150 may have access to the same social media account, e.g., via installation of an app or script at each client computing device 150. The interface management component 140 can also determine that multiple interfaces correspond to the same account, and can provide multiple, different content items to the multiple interfaces corresponding to the common account. For example, the data processing system 105 can determine, with end user consent, that an end user has accessed an account from different client computing devices 150. These multiple interfaces can be separate instances of the same interface (e.g., the same app installed on different client computing devices 150) or different interfaces such as different apps for different social media accounts that are both linked to a common email address account, accessible from multiple client computing devices 150.

The interface management component 140 can also determine or estimate distances between client computing devices 150 associated with candidate interfaces. For example, the data processing system 105 can obtain, with user consent, an indication that the input audio signal originated from a smartphone or virtual reality headset computing device 150, and that the end user is associated with an active smartwatch client computing device 150. From this information the interface management component can determine that the smartwatch is active, e.g., being worn by the end user when the end user enters the input audio signal into the smartphone, so that the two client computing devices 150 are within a threshold distance of one another (e.g., within 1 meter, 2 meters, 3 meters, 4 meters, or 7 meters; or within audio range or visual range). The data processing system 105 can also determine, with end user consent, the location of a smartphone that is the source of an input audio signal, and can also determine that a laptop account associated with the end user is currently active. For example, the laptop can be signed into a social media account indicating that the user is currently active on the laptop. In this example the data processing system 105 can determine that the end user is within a threshold distance of the smartphone and of the laptop, so that the laptop can be an appropriate choice for rendering of the content item via a candidate interface.

The interface management component 140 can identify one or more other computing devices 150 that are within a threshold distance of the computing device 150 that receives the input audio signal, and then poll candidate interfaces associated with the computing devices 150 that are within the threshold distance of the computing device 150. The interface management component 140 can be configured with one or more proximity detection techniques to identify the computing devices 150 that are within the threshold distance of the computing device 150 that receives the input audio signal. Proximity detection techniques can include, for example, a sub-audible wave technique, WIFI-based technique, Bluetooth-based technique, matching input audio signal-based technique, or a token-based technique. WIFI (or Wi-Fi) can refer to a technology for wireless local area networking with computing devices based on a standard.

For example, with end user consent the interface management component 140 can instruct a first computing device that receives the input audio signal to transmit a sub-audible wave to identify other computing devices within a threshold distance. A sub-audible wave can refer to an acoustic or audio transmission that cannot be perceived, or easily perceived, by a human ear. For example, the sub-audible wave can include infrasound, such as a sound wave that is lower in frequency than 20 Hz. The sub-audible wave can include ultrasound, such as a sound wave with frequencies higher than the upper audible limit of human hearing, such as greater than 20,000 Hz up to 1 gigahertz, 2 gigahertz, or more. If the second computing device can detect the sub-audible wave (or ultrasonic wave), then the second computing device can transmit a second sub-audible wave (or ultrasonic wave) in response. The second sub-audible wave can encode an identifier or other data to indicate or identify the second computing device. The first computing device can then receive the response from the second computing device to determine that the first and second computing devices are within a threshold distance because the first and second computing device were able to successfully transmit and receive sub-audible sound waves from one another. For example, the first computing device can decode the second sub-audible wave to extract the identifier of the second computing device. The first computing device can query the data processing system 105 to obtain information or profile information associated with the second computing device to facilitate transmission of content or notifications to the second computing device.

In some cases, a third computing device may receive the sub-audible wave transmitted by the first computing device. The third computing device can respond to the sub-audible wave with a third sub-audible wave encoded with a third identifier. The first computing device can receive the third sub-audible to determine that a third computing device is within range of the first computing device.

In some cases, the first computing device can transmit the sub-audible wave (or ultrasonic wave) with a token. The token can include a unique identifier. The token can be generated based on a hash function, for example using an n-tuple. The token can be generated based on one or more values, such as a current timestamp corresponding to the wave to be transmitted, a device identifier, an internet protocol address, or other parameters or values that can result in a unique identifier or token to facilitate the data processing system determining that the two or more computing devices are located within a threshold distance. The first computing device can record a first timestamp corresponding to transmission of the sub-audible wave with the token. The second computing device can detect the transmitted sub-audible signal and record a second timestamp corresponding to detection of the sub-audible wave. The first computing device can transmit, via network 165, an indication of the first time stamp and the token to the data processing system 105 (e.g., interface management component 140). The second computing device can receive the sub-audible wave and decode the wave to extract the token. Upon identifying the token, the second computing device can transmit, to the data processing system 105, the token and the second timestamp corresponding to detection (e.g., via sensor 151) or receipt of the sub-audible wave.

The data processing system 105 (e.g., interface management component 140) can receive the first timestamp and the token from the first computing device, and the second timestamp and the token from the second computing device. The data processing system 105 can match the token received from the first computing device with the token received from the second computing device because they may be the same token. Responsive to the token match, the data processing system 105 can retrieve the first and second timestamps in order to determine the distance between the two computing devices.

For example, the data processing system 105 (e.g., via interface management component 140) can determine a difference between the second timestamp and the first timestamp. The data processing system 105 can determine, based on the difference, a distance between the first computing device and the second computing device. For example, the difference can correspond to the amount of distance the sub-audible transmission travels. The sub-audible transmission can travel at the speed of sound, which can be roughly 340.29 meters per second. If the difference between the first time stamp and the second time stamp is 0.01 seconds, then the first computing device and the second computing device are approximately (e.g., plus or minus 10%) separated by 3.4 meters. In another example, if the difference between the first time stamp and the second time stamp is 0.001 seconds, then the first computing device and the second computing device are approximately separated by 0.34 meters. Thus, the data processing system 105 can multiply the speed of the sub-audible wave (e.g., the speed of sound) by the time difference to determine the distance between the computing devices. The data processing system 105 can compare the determined distance with a threshold distance (e.g., 1 meter, 2 meters, 3 meters, 4 meters, 5 meters, 7 meters, or more) to determine that the second computing device is within the threshold distance of the first computing device.

The interface management component 140 can use a proximity detection technique that utilizes a wireless signal. For example, the interface management component 140 can instruct the first computing device to transmit a wireless signal (e.g., radio frequency signal, Bluetooth signal, WIFI signal, beacon, near field communication signal, or low power Bluetooth signal). A device within range of the broadcast that receives the signal can respond to the first computing device, or transmit an indication to the interface management component 140 that indicates receipt of the signal. For example, the second computing device can broadcast a second signal that includes an identifier of the second computing device, and the first computing device can receive the second signal and extract the identifier of the second computing device to determine that the second computing device is within a threshold distance based on the success transmission. In another example, the second computing device can determine a power level of the broadcast signal to determine an approximate distance between the second computing device and the first computing device. For example, the power level of the broadcast signal can dissipate based on the distance the signal traverses. The power level of the broadcast signal can dissipate at a rate that is approximately inversely proportional to the square of the distance between the transmitter of the first computing device and the receiver of the second computing device (e.g., received power=transmitted power*(1/(4*pi*distance{circumflex over ( )}2))). The second computing device can detect the received power level of the signal, and provide the indication of the received power level to the first computing device or the data processing system 105 (e.g., interface management component 140) can compare the received signal power level with the transmitted power level to determine the distance between the first computing device and the second computing device.

The data processing system 105 (e.g., via interface management component 140) can determine that the first computing device and the second computing are within the threshold distance based on both the first computing device and the second computing device detecting a same input audio signal. For example, a first microphone of the first computing device can detect an input audio signal, and a second microphone of the second computing device can detect the same input audio signal at approximately the same time (e.g., difference in time may be due to a difference in respective distances between the source of the input audio signal and the first and second computing devices). The first computing device can provide the input audio signal detected by the first microphone to the data processing system 105, and the second computing device can provide the input audio signal detected by the second microphone to the data processing system 105. The data processing system 105 can then determine that both the first computing device and the second computing device detected the same input audio signal at approximately the same time. The data processing system 105 can further determine, based on respective timestamps corresponding to detection of the input audio signal by the first microphone and the second microphone, respectively, that the first and second computing devices are within a threshold distance.

By identifying a match between input audio signals detected by different computing devices, the data processing system 105 can determine that the different computing devices are in relatively close proximity to one another because their respective microphones were able to detect the same input audio signal. Detecting a match can include matching acoustic signatures, matching a Fourier transform of the audio signals, or converting the input audio signal to text using a speech-to-text technique and matching the text. The data processing system 105 can determine a match if the frequencies are substantially matching (e.g., 99% matching, 98% matching, 95% matching, 90% matching, 85% matching) or if the text is substantially matching (e.g., 99% matching, 98% matching, 95% matching, 90% matching, or 85% matching).

The interface management component 140 can use one or more proximity detection techniques to identify one or more computing devices within the threshold distance of a first computing device that receives the input audio signal. For example, the interface management component 140 can use a first proximity detection technique to identify a second computing device within the threshold distance from the first computing device. The interface management component 140 can use a second proximity detection technique to identify a third computing device within the threshold distance from the first computing device. The interface management component 140 can use a third proximity detection technique to identify a fourth computing device within the threshold distance from the first computing device. Each of the second, third and fourth computing devices can include a respective candidate interface. The data processing system 105 can poll the respective candidate interfaces to identify a resource utilization value for each of the candidate interfaces, and select one of the candidate interfaces based on a comparison of the respective resource utilization value. For example, the resource utilization value can indicate whether audio output is being transmitted via the interface (e.g., playing audio). If none of the candidate interfaces are playing audio output, then the data processing system 105 can select the candidate interface configured for audio output.

If there are multiple available interfaces that are configured for audio output, the data processing system 105 can use a policy or heuristic to select one or more of the interfaces for audio output. For example, the data processing system 105 can select the computing device having the audio interface that is closest to the first computing device to instruct to play audio content. The data processing system 105 can select the audio interface corresponding to the computing device that is actively being used by an end user. The data processing system 105 can select the audio interface corresponding to the computing device that was most recently used by the end user. The data processing system 105 can select the audio interface corresponding to the computing device having the greatest amount of battery remaining, or the computing device that is connected to a power source.

In some cases, the interface management component 140 retrieve, from memory (e.g., data repository 145), proximity information identifying a plurality of computing devices within the threshold distance of the computing device. For example, the data processing system 105 may have previously identified the plurality of computing devices and polled the candidate interfaces corresponding to the plurality of computing devices, and stored the information in the data repository 145. For example, one or more of the plurality of computing devices 150 may be stationary or fixed computing devices that are not typically moved (e.g., a television mounted to the wall; a desktop computing device; a home speaker; or a surround sound speaker system). Thus, the data processing system 105 may retrieve at least some information about the computing devices from memory. The data processing system 105 can then poll the candidate interfaces to determine a current or updated resource utilization value. Thus, the data processing system 105 may already have distance information or have previously determined that one or more computing devices are within range of a first computing device that receives the input audio signal, and may reduce additional resource utilization or delay by skipping the step to identify the devices and proceed to polling candidate interfaces.

The data processing system 105 can use a hierarchy of proximity detection techniques that are progressively more resource intensive to determine whether computing devices are within a threshold distance. For example, the data processing system 105 can first use a WIFI or internet protocol address based technique to determine whether the multiple computing devices are on the same network. If the computing devices are on separate WIFI networks associated with different IP addresses, the data processing system 105 can determine that the two devices are not within the threshold distance. If, however, the data processing system 105 determines that the two computing devices are on the same WIFI network, the data processing system can proceed to use a Bluetooth broadcast or beacon to determine whether the two computing devices are within Bluetooth range of one another. If the data processing system 105 determines that the two devices are within Bluetooth range, the data processing system 105 can proceed to instruct a first computing device to transmit a sub-audible sound wave to determine whether the computing devices are within the threshold distance. Thus, by utilizing a hierarchy of proximity detection techniques, the data processing system 105 can reduce resource utilization and reduce delay by using faster or less resource intensive proximity detection techniques to filter out devices that are outside the threshold distance, and then proceed to more granular proximity detection techniques that utilize more resources for computing devices that pass the broad proximity checks.

In some cases, the data processing system 105 can identify a second computing device having a second candidate interface that is within the threshold distance of the first computing device that receives the input audio signal. The data processing system 105 can query an application programming interface (“API”) executing on the second computing device to determine the second resource utilization value. For example, the second computing device can include an API that controls or monitors audio output, video output, volume level, or other information associated with the presentation of content. The API can response to the query by indicating a current volume level at which audio is being played; a duration of the audio content; a type of audio content (e.g., music, television, podcast, audio book, commercial, the second utilization value indicating a volume level at which audio content is played.

The interface management component 140 can use one or more techniques, policies or heuristics to select an interface from among the plurality of candidate interfaces, convert the content item to a modality compatible with the selected interface, and then transmit the converted content item for presentation via the selected interface. For example, the data processing system 105 can select an interface from the candidate interfaces based on a resource utilization value such as a sensor utilization value. The sensor can refer to a microphone of the computing device corresponding to the candidate interface. The microphone may detect low levels of ambient sound, indicating that audio is not being played proximate to the computing device and that the end user or other users are not speaking proximate to the computing device. The data processing system 105 can determine to select the interface because playing an audio file from the interface may not be redundant or duplicative of other audio content because the microphone has a low sensor utilization value.

In another example, sensor utilization can refer to a speaker of the computing device. The data processing system 105 can determine that the speaker is not being used, thereby indicating a low sensor utilization value. Accordingly, the data processing system 105 can select the speaker as the interface to provide the content item.

In another example, the sensor utilization can refer to a temperature of the computing device. For example, if the processor of the computing device is running at a temperature above a threshold, the data processing system 105 can determine that computing device is performing a processor intensive task, and may determine to not utilize that computing device or an interface of that computing device. Accordingly, the data processing system 105 can select an interface of another computing device within the threshold distance that has a lower temperature.

The interface management component 140 can select the interface for the content item based on at least one utilization value indicating that the selected interface is the most efficient for the content item. For example, from among candidate interfaces, the interface to render the content item at the smartwatch uses the least bandwidth due as the content item is smaller and can be transmitted with fewer resources. Or the interface management component 140 can determine that the candidate interface selected for rendering of the content item is currently charging (e.g., plugged in) so that rendering of the content item by the interface will not drain battery power of the corresponding client computing device 150. In another example, the interface management component 140 can select a candidate interface that is currently performing fewer processing operations than another, unselected interface of for example a different client computing device 150 that is currently streaming video content from the network 165 and therefore less available to render the content item without delay.

The interface management component 140 (or other data processing system 105 component) can convert the content item for delivery in a modality compatible with the candidate interface. For example, if the candidate interface is a display of a smartwatch, smartphone, or tablet computing device, the interface management component 140 can size the content item for appropriate visual display given the dimensions of the display screen associated with the interface. The interface management component 140 can also convert the content item to a packet or other protocol based format, including proprietary or industry standard format for transmission to the client computing device 150 associated with the selected interface. The interface selected by the interface management component 140 for the content item can include an interface accessible from multiple client computing devices 150 by the end user. For example, the interface can be or include a social media account that the end user can access via the client computing device 150 that originated the input audio signal (e.g., a smartphone) as well as other client computing devices such as tabled or desktop computers or other mobile computing devices.

The interface management component 140 can also select at least one candidate interface for the action data structure. This interface can be the same interface from which the input audio signal was obtained, e.g., a voice activated assistant service executed at a client computing device 150. This can be the same interface or a different interface than the interface management component 140 selects for the content item. The interface management component 140 (or other data processing system 105 components) can provide the action data structure to the same client computing device 150 that originated the input audio signal for rendering as audio output as part of the assistant service. The interface management component 140 can also transmit or otherwise provide the content item to the selected interface for the content item, in any converted modality appropriate for rendering by the selected interface.

Thus, the interface management component 140 can provide the action data structure as audio output for rendering by an interface of the client computing device 150 responsive to the input audio signal received by the same client computing device 150. The interface management component 140 can also provide the content item for rendering by a different interface of the same client computing device 150 or of a different client computing device 150 associated with the same end user. For example, the action data structure, e.g., “it will be sunny and 80 degrees at the beach on Saturday” can be provided for audio rendering by the client computing device as part of an assistant program interface executing in part at the client computing device 150, and the content item e.g., a text, audio, or combination content item indicating that “sunscreen is available from the convenience store near the beach” can be provided for rendering by an interface of the same or a different computing device 150, such as an email or text message accessible by the same or a different client computing device 150 associated with the end user. Separating the content item from the action data structure and sending the content item as, for example, a text message rather than an audio message can result in reduced processing power for the client computing device 150 that accesses the content item since, for example, text message data transmissions are less computationally intensive than audio message data transmissions. This separation can also reduce power usage, memory storage, or transmission bandwidth used to render the content item. This results in increased processing, power, and bandwidth efficiencies of the system 100 and devices such as the client computing devices 150 and the data processing system 105. This increases the efficiency of the computing devices that process these transactions, and increases the speed with which the content items can be rendered. The data processing system 105 can process thousands, tens of thousands or more input audio signals simultaneously so the bandwidth, power, and processing savings can be significant and not merely incremental or incidental.

The interface management component 140 can provide or deliver the content item to the same client computing device 150 (or a different device) as the action data structure subsequent to delivery of the action data structure to the client computing device 150. For example, the content item can be provided for rendering via the selected interface upon conclusion of audio output rendering of the action data structure. The interface management component 140 can also provide the content item to the selected interface concurrent with the provision of the action data structure to the client computing device 150. The interface management component 140 can provide the content item for delivery via the selected interface within a pre-determined time period from receipt of the input audio signal by the NLP component 110. The time period, for example, can be any time during an active length of the conversation of session. For example, if the input audio signal is “I would like to go to the beach this weekend” the pre-determined time period can be any time from receipt of the input audio signal through the end of the weekend, e.g., the active period of the conversation. The pre-determined time period can also be a time triggered from rendering of the action data structure as audio output by the client computing device 150, such as within 5 minutes, one hour or one day of this rendering.

The interface management component 140 can provide the action data structure to the client computing device 150 with an indication of the existence of the content item. For example, the data processing system 105 can provide the action data structure that renders at the client computing device 150 to provide the audio output “it will be sunny and 80 degrees at the beach on Saturday, check your email for more information.” The phrase “check your email for more information” can indicate the existence of a content item, e.g., for sunscreen, provided by the data processing system 105 to an interface (e.g., email). In this example, sponsored content can be provided as content items to the email (or other) interface and organic content such as the weather can be provided as the action data structure for audio output.

The data processing system 105 can also provide the action data structure with a prompt that queries the user to determine user interest in obtaining the content item. For example, the action data structure can indicate “it will be sunny and 80 degrees at the beach on Saturday, would you like to hear about some services to assist with your trip?” The data processing system 105 can receive another audio input signal from the client computing device 150 in response to the prompt “would you like to hear about some services to assist with your trip?” such as “sure”. The NLP component 110 can parse this response, e.g., “sure” and interpret it as authorization for audio rendering of the content item by the client computing device 150. In response, the data processing system 105 can provide the content item for audio rendering by the same client computing device 150 from which the response “sure” originated.

The data processing system 105 can delay transmission of the content item associated with the action data structure to optimize processing utilization. For example, the data processing system 105 provide the action data structure for rendering as audio output by the client computing device in real-time responsive to receipt of the input audio signal, e.g., in a conversational manner, and can delay content item transmission until an off-peak or non-peak period of data center usage, which results in more efficient utilization of the data center by reducing peak bandwidth usage, heat output or cooling requirements. The data processing system 105 can also initiate a conversion or other activity associated with the content item, such as ordering a car service responsive to a response to the action data structure or to the content item, based on data center utilization rates or bandwidth metrics or requirements of the network 165 or of a data center that includes the data processing system 105.

Based on a response to a content item or to the action data structure for a subsequent action, such as a click on the content item rendered via the selected interface, the data processing system 105 can identify a conversion, or initiate a conversion or action. Processors of the data processing system 105 can invoke the direct action API 135 to execute scripts that facilitate the conversion action, such as to order a car from a car share service to take the end user to or from the beach. The direct action API 135 can obtain content data 148 (or parameters 146 or policies 147) from the data repository 145, as well as data received with end user consent from the client computing device 150 to determine location, time, user accounts, logistical or other information in order to reserve a car from the car share service. Using the direct action API 135, the data processing system 105 can also communicate with the service provider computing device 160 to complete the conversion by in this example making the car share pick up reservation.

FIG. 2 depicts a flow diagram 200 for multi-modal transmission of packetized data in a voice activated computer network environment. The data processing system 105 can receive the input audio signal 205, e.g., “OK, I would like to go to the beach this weekend.” In response, the data processing system generates at least one action data structure 210 and at least one content item 215. The action data structure 205 can include organic or non-sponsored content, such as a response for audio rendering stating “It will be sunny and 80 degrees at the beach this weekend” or “high tide is at 3 pm.” The data processing system 105 can provide the action data structure 210 to the same client computing device 150 that originated the input audio signal 205, for rendering by a candidate interface of the client computing device 150, e.g., as output in a real time or conversational manner as part of of a digital or conversational assistant platform.

The data processing system 105 can select the candidate interface 220 as a selected interface for the content item 215, and can provide the content item 215 to the selected interface 220. The content item 215 can also include a data structure, which can be converted to the appropriate modality by the data processing system 105 for rendering by the selected interface 220. The content item 215 can include sponsored content, such as an offer to rent a beach chair for the day, or for sunscreen. The selected interface 220 can be part of or executed by the same client computing device 150 or by a different device accessible by the end user of the client computing device 150. Transmission of the action data structure 210 and the content item 215 can occur at the same time or subsequent to one another. The action data structure 210 can include an indicator that the content item 215 is being or will be transmitted separately via a different modality or format to the selected interface 200, alerting the end user to the existence of the content item 215.

The action data structure 210 and the content item 215 can be provided separately for rendering to the end user. By separating the sponsored content (content item 215) from the organic response (action data structure 210) audio or other alerts indicating that the content item 215 is sponsored do not need to be provided with the action data structure 210. This can reduce bandwidth requirements associated with transmission of the action data structure 210 via the network 165 and can simplify rendering of the action data structure 210, for example without audio disclaimer or warning messages.

The data processing system 105 can receive a response audio signal 225. The response audio signal 225 can include an audio signal such as, “great, please book me a hotel on the beach this weekend.” Receipt by the data processing system 105 of the response audio signal 225 can cause the data processing system to invoke the direct action API 135 to execute a conversion to, for example, book a hotel room on the beach. The direct action API 135 can also communicate with at least one service provider computing device 160 to provide information to the service provider computing device 160 so that the service provider computing device 160 can complete or confirm the booking process.

FIG. 3 depicts a method 300 of multi-modal transmission of packetized data in a voice activated computer network environment. The method 300 can receive data packets (ACT 305). For example, the NLP component 110, executed by the data processing system 105, can receive from the client computing device 105 data packets that include an input audio signal (ACT 305). The data packets can be received (ACT 305) via the network 165 as packet or other protocol based data transmissions. The method 300 can identify, from the input audio signal, requests or trigger keywords corresponding to the requests (ACT 310). For example, the NLP component 110 can parse the input audio signal to identify requests that relate to subject matter of the input audio signal, or to identify trigger keywords that can indicate, for example, actions associated with the requests.

The method 300 can generate at least one action data structure (ACT 315). For example, the direct action API 135 can generate action data structures (ACT 315) based on the requests or trigger keywords. The action data structures can indicate organic or non-sponsored content related to the input audio signal. The method 300 can select at least one content item (ACT 320). For example, the content selector component 125 can receive the request(s) or the trigger keyword(s) and based on this information can select one or more content items. The content items can include sponsored items having subject matter that relates to subject matter of the request or of the trigger keyword. The content items can be selected by the content selector component 125 via a real-time content selection process.

The method 300 can identify a plurality of computing devices within a threshold range of the computing device, and poll a plurality of interfaces to determine at least one candidate interface (ACT 325). The method 300 can use one or more proximity detection technique to identify the one or more computing devices within the threshold range, and then poll candidate interfaces associated with the one or more computing devices. The candidate interfaces can include candidate interfaces for rendering of the selected content item (or action data structure). For example, the interface management component 140 can query interfaces to obtain utilization values, e.g., parameter information or other characteristics about the interfaces (ACT 330). Based on the utilization values the interface management component 140 can select (ACT 335) at least one candidate interface as a selected interface for rendering of the content item (or of the action data structure). The method 300 can include converting the content item to a modality for rendering via the selected interface (ACT 340). For example the data processing system 105 or component thereof such as the interface management component 140 can convert the content item for rendering in a content item slot of an online document (e.g., for display as an email (e.g., via a selected email interface) or as a text message for display in a chat app). In some cases, the method 300 can include selecting the content item in the modality for rendering via the selected interface (ACT 340).

The method 300 can provide the action data structure to the client computing device 150 for rendering (ACT 345) and can transmit the content item to the candidate interface selected for rendering of the content item (ACT 350). For example, via the interface 115 the interface management component 140 can provide the action data structure to the client computing device 150 for rendering as audio output responsive to the input audio signal (ACT 345). The data processing system can also transmit the content item to the selected interface on the same or a different client computing device 150 for rendering in the converted modality (ACT 350).

FIG. 4 depicts an illustrative operation of a system of multi-modal transmission of packetized data in a voice activated computer network environment. The system 400 can include one or more component depicted in system 100, 200 or 600, including, for example, a data processing system 105, network 165 and one or more computing devices.

Is illustrated in FIG. 4, system 400 can include a first computing device 404 that is a distance 410 away from a second computing device 406. The second computing device 406 can be communicatively coupled to the first output device 408 in order to output audio, video, images or other content via first output device 408. The first computing device 405, second computing device 406 and first output device 408 can be positioned or placed in a first room 402 (e.g., a room of a house, apartment, dwelling, office, hotel room or other physical space). The first computing device 404 and second computing device 406 can interact or communicate with a data processing system 105 via network 165.

System 400 can include one or more computing devices having one or more user interfaces. A first user interface can be considered invasive, such as a user interface element that appears without a user requesting the user interface element. These user interface elements can include content items or notifications, and can be provided via a mobile application or web page. Such user interface elements may be ignored or dismissed as they may be visually invasive user interface elements. Some computing devices may be primarily audio or audio only devices, such as a voice-based digital assistant. In these types of computing devices, the user interface element may include playback of audio, which may interrupt content the device was outputting prior to the notification or content item. As such, the systems and methods of the present disclosure can provide these notifications at specific times or specific interfaces or specific computing devices, such as without interrupting current output or playing over the current device's audio channel or a nearby device's audio channel.

The data processing system 105 can determine when and where to deliver content items or notifications. The data processing system 105 can provide a mechanism for determining when to engage a user with an audio driven notification based on user engagement with nearby devices and the media playback state of those nearby devices. For example, the data processing system 105 can determine if the user is already engaged with a nearby computing device (e.g., a second computing device 406 playing a video on a first output device 408, such as a monitor, display device, television, or speaker) and chooses not to interrupt the user with an audio based promotion.

The data processing system 105 can determine to either not show the content item or notification at all, or to send the notification or content item to a different medium or device (e.g., sending the content item or notification as a push notification to a first computing device 404), or determine to delay the content item or notification for later delivery.

For example, the system 400 can include a first computing device 404. The first computing device 404 can include one or more component or functionality of computing device 150. The first computing device 404 can receive an input audio signal comprising voice input or an audio command provided by user. The first computing device 404 can engage with the audio command, and then either plays or withholds a content item or notification based on the determination made by the data processing system 105. The data processing system 105 can determine to instruct the first computing device 105 to play or present the content item or notification if the user is present and the first computing device 404 is not interrupting another activity. The data processing system 105 can determine the user present based on an interaction or engagement with the first computing device 404.

The data processing system 105 can further determine whether the content item or notification would interrupt another activity. For example, the data processing system 105 can determine the audio state of nearby devices through a local API. The data processing system 105 can use the API to query the second computing device 406 to determine whether the second computing device 406 is currently playing audio content via the first output device 408 and what the volume level is. The data processing system 105 can inspect or process the metadata about the content currently being played by the second computing device 406 to determine if the content includes audio or does not include audio (e.g., playing a picture slide show for without audio). If the second computing device 406 is not playing audio, then the data processing system 105 can determine that providing an audio content item for presentation via the first computing device 404 may not interrupt the content presented by the second computing device 406.

To do so, the data processing system 105 can detection computing devices within a threshold distance of the first computing device 404. The data processing system 105 (e.g., an interface management component) can utilize one or more proximity detection techniques to determine a distance 410 between the first computing device 404 and the second computing device 406, and determine if distance 410 is within a threshold distance. For example, the data processing system 105 can instruct the first computing device 404 to transmit a sub-audible sound wave. By sending a token through a sub-audible sound from speakers of the first computing device 404 to another device's microphone (e.g., microphone of the second computing device 406) and then comparing the value of that token with a server exchange, the data processing system 105 can determine if the first computing device 404 and the second computing device 406 are in a same room (e.g., a first room 402). The data processing system 105 can further approximate the distance 410 between two devices 404 and 406, which can synchronized clocks, by counting the milliseconds it takes for the token to travel from the speaker of the first computing device 404 to the microphone of the second computing device 406.

In some cases, the data processing system 105 can determine that audio or video is played on a nearby device (e.g., within a threshold distance such as distance 410) of the first computing device 404, and determine block the provision of an audio content item or notification via the first computing device 404. In some cases, the data processing system 105 can determine to override the block based on an override configuration of the first computing device 404 (e.g., override block to provide security alerts).

FIG. 5 depicts an illustrative operation of a system of multi-modal transmission of packetized data in a voice activated computer network environment. The system 500 can include one or more component depicted in system 100, 200 or 600, including, for example, a data processing system 105, network 165 and one or more computing devices. System 500 can include first computing device 404, second computing device 406, and first output device 408. System 500 can include a third computing device 504, which can include one or more component or functionality of computing device 150. System 500 can include a second output device 506, which can include one or more component or functionality of the first output device 408.

Is illustrated in FIG. 5, system 500 can include a first computing device 404 that is a distance 410 away from a second computing device 406. The second computing device 406 can be communicatively coupled to the first output device 408 in order to output audio, video, images or other content via first output device 408. The first computing device 405, second computing device 406 and first output device 408 can be positioned or placed in a first room 402 (e.g., a room of a house, apartment, dwelling, office, hotel room or other physical space). The first computing device 404 and second computing device 406 can interact or communicate with a data processing system 105 via network 165.

System 500 can include a second room 502 that is positioned adjacent to the first room 402. The second room 502 can be separated, at least in part, from the first room 402 by a wall 512. The wall 512 can include an opening 514 or doorway. In the second room 502, the system 500 can include a fourth computing device 510, and a third computing device 504 communicatively coupled to a second output device 506. The third computing device 504 can be separated from the first computing device 404 by a distance 508.

The data processing system 105 can provide content or notifications on one or more computing devices in environments where one or more devices have a relatively high resource utilization value (e.g., are playing audio or video) without disrupting the resource. For example, the data processing system 105 can select a content item and determine to block provision of the content item on the first output device 408 via the second computing device 406 because the second computing device 406 is playing a video with audio. Instead, the data processing system 105 can determine to provide the content item or notification via a push notification to a mobile computing device (e.g., a first computing device 404) that is within the threshold distance from the second computing device 406.

The data processing system 105 can use one or more proximity detection techniques (e.g., sub-audible sound waves, Bluetooth, or detection of a same audio-based input signal on separate devices) to identify nearby computing devices within a threshold distance. Bluetooth can refer to a short-range wireless transmission standard for interconnection of computing devices, such as mobile phones, computers or other electronic devices. The short-range wireless transmission can utilize radio waves from 2.4 to 2.485 GHz. The range can be approximately 0.5 meters, 1 meters, 10 meters, 100 meters, 150 meters, 240 meters, or more, for example. For example, detecting the same input audio signal (or audio command) by two separate devices (e.g., a first computing device 404 and a second computing device 406) can be a proxy signal that the devices are within a threshold distance.

The data processing system 105 can identify a content item or notification to transmit to a computing device. Responsive to identifying the content item or notification, the data processing system 105 can determine whether one or more computing devices are within the threshold distance. In some instances proximity information can already stored in data processing system 105, or broad proximity information can be used to identify that the two devices are not close enough to test more granular device proximity (e.g., sub-audible sounds). For example, the data processing system 105 can use a hierarchy of proximity detection techniques that are progressively more resource intensive to determine whether computing devices are within a threshold distance.

In some cases, the data processing system 105 can identify multiple computing devices that are linked with an account. The data processing system 105 can then identify a set of nearby devices within a threshold distance. For example, as illustrated in FIG. 500, the data processing system 105 can use one or more proximity detection techniques to determine that the distance 508 between the first computing device 404 and the third computing device 504 is greater than the threshold distance. The data processing system 105 can determine the a user is interacting with the third computing device 504 to play a video on the second output device 506. The data processing system 105 can determine not to provide audio content or a notification for presentation via the first computing device 404 because the third computing device 504 with which the user is engaged or interacting is greater than the threshold distance from the first computing device 404.

In some cases, the data processing system 105 can identify one or more applications as candidate interfaces to present content or a notification. For example, the data processing system 105 can determine to leverage an application integrated with the first computing device 404 to provide the content or notification. The data processing system 105 can identify multiple applications integrated with the first computing device 404 that can provide the content or notification, de-duplicate the applications, and select a candidate interface (e.g., application) based on resource utilization values or a pre-programmed hierarchy based on a notification configuration (e.g., audio interface can rank higher than image interface which can rank higher than text-only interfaces).

Thus, the data processing system can send notification to the selected device. This notification can include a payload. For example, the first computing device can transmit a notification to a fourth computing device 510 (e.g., a mobile computing device 150) promoting new content that can be streamed to the third computing device 504 for presentation via second output device 506. The user can command, instruct or indicate to the fourth computing device 510, responsive to the notification, to start streaming the new content on the second output device 506.

FIG. 6 is a block diagram of an example computer system 600. The computer system or computing device 600 can include or be used to implement the system 100, or its components such as the data processing system 105. The computing system 600 includes a bus 605 or other communication component for communicating information and a processor 610 or processing circuit coupled to the bus 605 for processing information. The computing system 600 can also include one or more processors 610 or processing circuits coupled to the bus for processing information. The computing system 600 also includes main memory 615, such as a random access memory (RAM) or other dynamic storage device, coupled to the bus 605 for storing information, and instructions to be executed by the processor 610. The main memory 615 can be or include the data repository 145. The main memory 615 can also be used for storing position information, temporary variables, or other intermediate information during execution of instructions by the processor 610. The computing system 600 may further include a read only memory (ROM) 620 or other static storage device coupled to the bus 605 for storing static information and instructions for the processor 610. A storage device 625, such as a solid state device, magnetic disk or optical disk, can be coupled to the bus 605 to persistently store information and instructions. The storage device 625 can include or be part of the data repository 145.

The computing system 600 may be coupled via the bus 605 to a display 635, such as a liquid crystal display, or active matrix display, for displaying information to a user. An input device 630, such as a keyboard including alphanumeric and other keys, may be coupled to the bus 605 for communicating information and command selections to the processor 610. The input device 630 can include a touch screen display 635. The input device 630 can also include a cursor control, such as a mouse, a trackball, or cursor direction keys, for communicating direction information and command selections to the processor 610 and for controlling cursor movement on the display 635. The display 635 can be part of the data processing system 105, the client computing device 150 or other component of FIG. 1, for example.

The processes, systems and methods described herein can be implemented by the computing system 600 in response to the processor 610 executing an arrangement of instructions contained in main memory 615. Such instructions can be read into main memory 615 from another computer-readable medium, such as the storage device 625. Execution of the arrangement of instructions contained in main memory 615 causes the computing system 600 to perform the illustrative processes described herein. One or more processors in a multi-processing arrangement may also be employed to execute the instructions contained in main memory 615. Hard-wired circuitry can be used in place of or in combination with software instructions together with the systems and methods described herein. Systems and methods described herein are not limited to any specific combination of hardware circuitry and software.

Although an example computing system has been described in FIG. 6, the subject matter including the operations described in this specification can be implemented in other types of digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this specification and their structural equivalents, or in combinations of one or more of them.

For situations in which the systems discussed herein collect personal information about users, or may make use of personal information, the users may be provided with an opportunity to control whether programs or features that may collect personal information (e.g., information about a user's social network, social actions or activities, a user's preferences, or a user's location), or to control whether or how to receive content from a content server or other data processing system that may be more relevant to the user. In addition, certain data may be anonymized in one or more ways before it is stored or used, so that personally identifiable information is removed when generating parameters. For example, a user's identity may be anonymized so that no personally identifiable information can be determined for the user, or a user's geographic location may be generalized where location information is obtained (such as to a city, postal code, or state level), so that a particular location of a user cannot be determined. Thus, the user may have control over how information is collected about him or her and used by the content server.

The subject matter and the operations described in this specification can be implemented in digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this specification and their structural equivalents, or in combinations of one or more of them. The subject matter described in this specification can be implemented as one or more computer programs, e.g., one or more circuits of computer program instructions, encoded on one or more computer storage media for execution by, or to control the operation of, data processing apparatuses. Alternatively or in addition, the program instructions can be encoded on an artificially generated propagated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal that is generated to encode information for transmission to suitable receiver apparatus for execution by a data processing apparatus. A computer storage medium can be, or be included in, a computer-readable storage device, a computer-readable storage substrate, a random or serial access memory array or device, or a combination of one or more of them. While a computer storage medium is not a propagated signal, a computer storage medium can be a source or destination of computer program instructions encoded in an artificially generated propagated signal. The computer storage medium can also be, or be included in, one or more separate components or media (e.g., multiple CDs, disks, or other storage devices). The operations described in this specification can be implemented as operations performed by a data processing apparatus on data stored on one or more computer-readable storage devices or received from other sources.

The terms “data processing system” “computing device” “component” or “data processing apparatus” encompass various apparatuses, devices, and machines for processing data, including by way of example a programmable processor, a computer, a system on a chip, or multiple ones, or combinations of the foregoing. The apparatus can include special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit). The apparatus can also include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, a cross-platform runtime environment, a virtual machine, or a combination of one or more of them. The apparatus and execution environment can realize various different computing model infrastructures, such as web services, distributed computing and grid computing infrastructures. The interface management component 140, direct action API 135, content selector component 125, prediction component 120 or NLP component 110 and other data processing system 105 components can include or share one or more data processing apparatuses, systems, computing devices, or processors.

A computer program (also known as a program, software, software application, app, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program can correspond to a file in a file system. A computer program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub-programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.

The processes and logic flows described in this specification can be performed by one or more programmable processors executing one or more computer programs (e.g., components of the data processing system 105) to perform actions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatuses can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit). Devices suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.

The subject matter described herein can be implemented in a computing system that includes a back-end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front-end component, e.g., a client computer having a graphical user interface or a web browser through which a user can interact with an implementation of the subject matter described in this specification, or a combination of one or more such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks).

The computing system such as system 100 or system 600 can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network (e.g., the network 165). The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. In some implementations, a server transmits data (e.g., data packets representing action data structures or content items) to a client device (e.g., to the client computing device 150 for purposes of displaying data to and receiving user input from a user interacting with the client device, or to the service provider computing device 160 or the content provider computing device 155). Data generated at the client device (e.g., a result of the user interaction) can be received from the client device at the server (e.g., received by the data processing system 105 from the computing device 150 or the content provider computing device 155 or the service provider computing device 160).

While operations are depicted in the drawings in a particular order, such operations are not required to be performed in the particular order shown or in sequential order, and all illustrated operations are not required to be performed. Actions described herein can be performed in a different order.

The separation of various system components does not require separation in all implementations, and the described program components can be included in a single hardware or software product. For example, the NLP component 110, the content selector component 125, the interface management component 140, or the prediction component 120 can be a single component, app, or program, or a logic device having one or more processing circuits, or part of one or more servers of the data processing system 105.
